Do You Unplug While On Vacation?

I'm leaving for a weekend getaway tomorrow — I'm finally going to check out a city that I've read so much about and have dreamed about visiting for years and years. I was actually planning on moving there for college (instead of Philadelphia). I'm visiting San Francisco tomorrow and I'm contemplating unplugging everything.

Everything meaning — everything but the important stuff like refrigerator/freezer and AC. I've done this in the past for extended trips (over a week), but I've never done it for such a short trip. I'm wondering if it will be worth it, or if I'm just thinking about it too much.

It's not as if I have a house full of electronics that would be sapping the world of its energy, but, I know that the little things count. If I unplug my entertainment center, all of the lamps (except for a few for the cats) and turn the AC to a reasonable temperature (something I always do when I leave town) — I should feel much better about not being such an energy hog.

So, I was wondering — do other people unplug their electronics for just weekend getaways?
